Hydrogen peroxide mixed with vinegar makes peracetic acid, which is a toxic gas that irritates the skin and respiratory system
Most covalent compounds have relatively low melting points and boiling points. Covalent compounds usually have lower enthalpies of fusion and vaporization than ionic compounds. Covalent compounds tend to be more flammable than ionic compounds. When dissolved in water, they don't conduct electricity.

Answer:
The reaction type is double displacement
Ethene belongs to class of
unsaturated hydrocarbons called as
Alkenes. Alkene contains a
double bond between two carbon atoms. And the general formula for alkene is,
CnH2nWhereas in Ethene, n = 2, so
C₂H₄
Therefore, in ethene there are two carbon atoms doubly bonded to each other via
one sigma and
one pi bond. Also each carbon atom is further covalently bonded to
two hydrogen atoms via sigma bond as shown below,
